Define a new qc_stream_desc flag QC_SD_FL_OOB_BUF. This is to mark streams which are not subject to the connection limit on allocated MUX stream buffer. The purpose is to simplify handling of QUIC MUX streams which do not transfer data and as such are not driven by haproxy layer, for example HTTP/3 control stream. These streams interacts synchronously with QUIC MUX and cannot retry emission in case of temporary failure. This commit will be useful once connection buffer allocation limit is reimplemented to directly rely on the congestion window size. This will probably cause the buffer limit to be reached more frequently, maybe even on QUIC MUX initialization. As such, it will be possible to mark control streams and prevent them to be subject to the buffer limit. QUIC MUX expose a new function qcs_send_metadata(). It can be used by an application protocol to specify which streams are used for control exchanges. For the moment, no such stream use this mechanism.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
